A Study of Dual Active Bridge Converter Performance

Dual Active Bridge (DAB) converter is the most prominent topology of Isolated Bidirectional DC-DC (IBDC) converters. This type of DAB converter serves as interface between the energy storage devices for renewable energy systems applications and, highly applied in automotive applications like electric, hybrid and fuel cell vehicles and aerospace applications and personal electronic equipment. Hence, this type of DAB converter topology requires detail methodical study in terms of its reliability, efficiency, safety and durable performance operation. The aim of this work is to learn the working principle, performance of operation, design and case study simulation to validate DAB converter. DAB converter allows the power to flow in both directions between the two energy sources. Different type of these converter topologies will provide different functions and services in accordance to their structure and components, which depends upon the applications. Hence, they are widely used.
